public abstract static class Type . SchemalessStruct implements Type , SqlType . Struct
This is a special version of struct that is intended to only be used in the com.google.cloud.bigtable.data.v2.models.sql.StructReader getters that require types. We don't
want users to need to specify the struct schema when the schema will be validated on calls to
com.google.cloud.bigtable.data.v2.models.sql.StructReader methods on the struct.
Any attempts to interact with the schema will throw an exception.
For example the historical map data type uses this as follows:
Map<ByteString , List<Struct> > historicalMap =
resultSet . getMap (
"cf ",
SqlType . mapOf ( SqlType . bytes (), SqlType . arrayOf ( SqlType . struct ())));
Struct struct = historicalMap . get ( "column "). get ( 0 );
// Struct schema will be validated here so there's no need for users to pass the schema to getMap above
ByteString value = struct . getBytes ( "value ");
